As one of important clothing accessories,the close material has a very important status in the clothing.
闭合材料作为一种重要的服装辅料,在服装中的地位相当重要。
Based on simplified consolidation theory of unsaturated soils, the whole process of formation, propagation and close-up of cracks in clay surface during a drying and wetting cycle were simulated successfully in this paper.
在非饱和土简化固结理论基础上,对粘土在干湿过程中,表面裂缝从形成、发展到闭合的发展过程进行了数值模拟,模拟结果说明,本文采用的基于非饱和简化固结理论的计算方法是可行、实用的。
However,the closure problem makes it impossible to compare directly the compositions of the altered rocks with those of the fresh rocks.
针对流体与岩石之间在反应 (蚀变 )过程中普遍存在的闭合问题 ,指出不能直接比较蚀变前后岩石成分的质量 ,而需要进行质量平衡计算 ,在这种计算中 ,首先要有合理的假设前提 ,即已知岩石质量变化前后的体积变化 ,或者岩石在质量变化中存在着不活动元素。
